Use binding dimensions and metrics

Customer Journey Analytics offers several ways to persist dimension values beyond the hit that they are set on. One of the persistence methods that Adobe offers is known as Binding. In previous versions of Adobe Analytics, this concept was known as merchandising.

While you can use binding dimensions with top-level event data, this concept is best used when working with Arrays of objects. You can attribute a dimension to one part of an object array without applying the dimensoon to all attributes in a given event. For example, you can attribute a search term to one product in your shopping cart object array without binding that search term to the entire event.

Example 1: Use binding dimensions to attribute additional product attributes to a purchase

You can bind dimension items within an object array to another dimension. When the bound dimension item appears, Customer Journey Analytics recalls the bound dimension and includes it in the event for you. Consider the following customer journey:

  1. A visitor views a product page on a washing machine.

    code language-json
    {
        "PersonID": "1",
        "product": [
            {
                "name": "Washing Machine 2000",
                "color": "white",
                "type": "front loader",
            },
        ],
        "timestamp": 1534219229
    }
    
  2. The visitor then views a product page on a dryer.

    code language-json
    {
        "PersonID": "1",
        "product": [
            {
                "name": "Dryer 2000",
                "color": "neon orange",
            },
        ],
        "timestamp": 1534219502
    }
    
  3. Ultimately they make a purchase. The color of each product was not included in the purchase event.

    code language-json
    {
        "PersonID": "1",
        "orders": 1,
        "product": [
            {
                "name": "Washing Machine 2000",
                "price": 1600,
            },
            {
                "name": "Dryer 2000",
                "price": 499
            }
        ],
        "timestamp": 1534219768
    }
    

If you wanted to look at revenue by color without a binding dimension, the dimension product.color persists and incorrectly attributes credit to the dryer’s color:

product.color
revenue
neon orange
2099

Go into Data views and bind the Product Color dimension to Product Name:

Binding dimension

When you set this persistence model, Customer Journey Analytics takes note of the product name whenever the product color is set. When it recognizes the same product name in a subsequent event for this person, the product color is brought over as well. The same data when you bind product color to product name would look similar to the following:

product.color
revenue
white
1600
neon orange
499

Example 2: Use binding metrics to tie a search term to a product purchase

One of the most common merchandising methods in Adobe Analytics has been to bind a search term to a product so each search term gets credit for its appropriate product. Consider the following customer journey:

  1. A visitor arrives to your site and searches for boxing gloves. The searches metric increments by one, and the top three search results are displayed.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Search results",
        "search": "1",
        "search_term": "boxing gloves",
        "product": [
            {
                "name": "Beginner gloves",
            },
            {
                "name": "Tier 3 gloves",
            },
            {
                "name": "Professional gloves",
            }
        ]
    }
    
  2. They find a pair of gloves that they like, and add it to their cart.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Shopping cart",
        "cart_add": "1",
        "product": [
            {
                "name": "Tier 3 gloves",
            }
        ]
    }
    
  3. The visitor then searches for tennis racket. The searches metric increments by one, and the top three search results are displayed.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Search results",
        "search": "1",
        "search_term": "tennis racket",
        "product": [
            {
                "name": "Shock absorb racket",
            },
            {
                "name": "Women's open racket",
            },
            {
                "name": "Extreme racket",
            }
        ]
    }
    
  4. They find a racket that they like, and add it to their cart.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Shopping cart",
        "cart_add": "1",
        "product": [
            {
                "name": "Tier 3 gloves",
            },
            {
                "name": "Shock absorb racket",
            }
        ]
    }
    
  5. The visitor searches a third time for shoes. The searches metric increments by one, and the top three search results are displayed.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Search results",
        "search": "1",
        "search_term": "shoes",
        "product": [
            {
                "name": "Men's walking shoes",
            },
            {
                "name": "Tennis shoes",
            },
            {
                "name": "Skate shoes",
            }
        ]
    }
    
  6. They find a pair of shoes that they like, and add it to their cart.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Shopping cart",
        "cart_add": "1",
        "product": [
            {
                "name": "Tier 3 gloves",
            },
            {
                "name": "Shock absorb racket",
            },
            {
                "name": "Skate shoes",
            }
        ]
    }
    
  7. The visitor goes through the checkout process and purchases these three items.

    code language-json
    {
        "PersonID": "1",
        "page_name": "Thank you for your purchase",
        "purchase": "1",
        "product": [
            {
                "name": "Tier 3 gloves",
                "price": "89.99"
            },
            {
                "name": "Shock absorb racket",
                "price": "34.99"
            },
            {
                "name": "Skate shoes",
                "price": "79.99"
            }
        ]
    }
    

If you use an allocation model that does not include a binding dimension with search term, all three products attribute revenue to only a single search term. For example, if you used Original allocation with the search term dimension:

search_term
revenue
boxing gloves
$204.97

If you used Most Recent allocation with the search term dimension, all three products still attribute revenue to a single search term:

search_term
revenue
shoes
$204.97

While this example includes only one person, many persons who search for different things can misattribute search terms to different products. Multiple persons search for different things make it difficult to determine what the best search results actually are.

You can now bind Search Term to Product Name whenever the Searches metric is present to attribute the search term correctly to revenue.

Binding metric

In Analysis Workspace, the resulting report would look similar to the following:

search_term
revenue
boxing gloves
$89.99
tennis racket
$34.99
shoes
$79.99

Customer Journey Analytics automatically detects the relationship between the selected dimension and the binding dimension. If the binding dimension is in an object array while the selected dimension is at a higher level, a binding metric is required. A binding metric acts as a trigger for a binding dimension, so it only binds itself on events where the binding metric is present. In the above example, the search results page always includes a search term dimension and a searches metric.

Setting the search term dimension to this persistence model executes the following logic:

  • When the search term dimension is set, check for the presence of a product name.
  • If the product name is not there, do nothing.
  • If the product name is there, check for the presence of the Searches metric.
  • If the Searches metric is not there, do nothing.
  • If the Searches metric is there, bind the search term to all product names in that event. It copies itself down to the same level as the product name for that event. In this example, it is treated as product.search_term.
  • If the same product name is seen in a subsequent event, the bound search term is carried forward to that event as well.

Example 3: Bind video search term to user profile

You can bind a search term to a user profile so persistence between profiles remains completely separated. For example, your organization runs a streaming service where an overarching account can have multiple profiles. The visitor has a child profile and an adult profile.

  1. The account logs in under the child profile and searches for a kid’s TV show. Note that the "ProfileID" is 2 to represent the child profile.

    code language-json
    {
        "PersonID": "7078",
        "ProfileID": "2",
        "Searches": "1",
        "search_term": "kids show"
    }
    
  2. They find the show “Orangey” and play it so their child can watch it.

    code language-json
    {
        "PersonID": "7078",
        "ProfileID": "2",
        "ShowName": "Orangey",
        "VideoStarts": "1"
    }
    
  3. Later that evening, the parent switches to their profile and searches for adult content to watch. Note that the "ProfileID" is 1 to represent the adult profile. Both profiles belong to the same account, represented by the same "PersonID".

    code language-json
    {
        "PersonID": "7078",
        "ProfileID": "1",
        "Searches": "1",
        "search_term": "grownup movie"
    }
    
  4. The find the show “Analytics After Hours” and enjoy their evening watching it.

    code language-json
    {
        "PersonID": "7078",
        "ProfileID": "1",
        "ShowName": "Analytics After Hours",
        "VideoStarts": "1"
    }
    
  5. The next day, they continue the show “Orangey” for their child. They do not need to search since they are now already aware of the show.

    code language-json
    {
        "PersonID": "7078",
        "ProfileID": "2",
        "ShowName": "Orangey",
        "VideoStarts": "1"
    }
    

If you use Most Recent allocation with Person expiration, the grownup movie search term is attributed to the last view of the kid’s show.

Search term
Video starts
grownup movie
2
kids show
1

However, if you bound search_term to ProfileID, each profile’s searches would be isolated to their own profile, attributed to the correct shows that they search for.

Visitor binding

Analysis Workspace attributes the second episode of Orangey to the search term kids show without taking searches from other profiles into account.

Search term
Video starts
kids show
2
grownup movie
1

Example 4: Evaluate browse vs. search behavior in a retail setting

You can bind values to dimensions set on previous events. When you set a variable with a binding dimension, Customer Journey Analytics takes into account the persisted value. If this behavior is undesired, you can adjust the binding dimension’s persistence settings. Consider the following example where product_finding_method is set on an event, then bound to the Cart Adds metric on the following event.

  1. A visitor performs a search for camera. Note that no products are set on this page.

    code language-json
    {
        "search_term": "camera",
        "product_finding_method": "search"
    }
    
  2. They click on a camera that they like and add it to their cart.

    code language-json
    {
        "Product": [
            {
                "name": "DSLR Camera"
            }
        ],
        "CartAdd": "1"
    }
    
  3. The visitor then browses into the men’s belts category without performing a search. Note that no products are set on this page.

    code language-json
    {
        "category": "Men's belts",
        "product_finding_method": "browse"
    }
    
  4. They click on a belt that they like and add it to their cart.

    code language-json
    {
        "Product": [
            {
                "name": "Ratchet belt"
            }
        ],
        "CartAdd": "1"
    }
    
  5. They go through the checkout process and purchase these two items.

    code language-json
    {
        "Product": [
            {
                "name": "DSLR Camera",
                "price": "399.99"
            },
            {
                "name": "Ratchet belt",
                "price": "19.99"
            }
        ],
        "Purchase": "1"
    }
    

If persistence is set to most recent allocation without a binding dimension, all $419.98 of revenue is attributed to the browse finding method.

If persistence is set using original allocation without a binding dimension, all $419.98 of revenue is attributed to the search finding method.

However, if you bind product_finding_method to the Cart Adds metric, the resulting report attributes each product to the correct finding method.
